Into Unscientific Chapter 288

  Chapter 288 A one-year appointment! (7.6k)

  In Faraday's office.

  Hearing Xu Yun's words, 'Do you want to understand the meaning of computers and really live? 'after.

  Babbage, Ada, and Earl Lovelace showed a trace of doubt almost simultaneously:

   Who is this forcing?

  This person can not only sit side by side with Gauss Faraday, but also dare to speak before these two big shots.

  If it weren't for the inability of same-sex couples to have children these days, Babbage probably would have regarded Xu Yun as the crystallization of the love between Faraday and Gauss.

  Then he glanced at Xu Yun cautiously, and when his eyes met, he quickly looked away and asked:

   "Sir, what do you mean by this?"

   "Just call me Luo Feng, Mr. Charles."

  Xu Yun briefly introduced himself, then paused, and continued:

   "My point is actually very simple - interested in making a deal?"

  Babbage and Ada looked at each other, and their expressions gradually became serious:

   "What deal?"

  Xu Yun smiled slightly at him, stretched out a finger, and explained:

   "Trinity College will invest in your project with a sum of no less than 50,000 pounds, and you will manufacture an analytical machine according to the requirements of the college."

  Babbage didn't lose his face when he heard the words, but looked at Gauss and Faraday.

  Xu Yun's words themselves are not a problem, but when they are spoken from a young man like Xu Yun, the problem is very serious.

   Seeing Babbage's eyes constantly drifting towards him, Gauss couldn't help explaining:

   "Mr. Charles, Luo Feng is the initiator of this investment. What he says can fully represent the will of the Cambridge School Board."

   Babbage was stunned for a moment.

   On the way to Cambridge, he once discussed with the Ada couple the reasons behind the invitation from Cambridge University.

  The three complement each other and make various judgments about possible situations.

  For example, Ada guessed that Prince Albert might be interested in the Analytical Engine, so he invited himself to come over for a detailed discussion in the name of Cambridge University.

  Babbage thinks that William Whewell, the dean of Trinity College, may have persuaded the school board—William Whewell and William Herschel were a pair of close friends, and they were both pioneers of hypotheticalism.

  As for Babbage, he is also close friends with William Herschel's son John Herschel, who has helped him a lot in the past few years.

  John Herschel persuaded Whewell through his father, and then Whewell persuaded the school board. This possibility still exists.

  Even Earl Lovelace opened his head wide open, and proposed a weird idea:

   Could it be that the astrological fortuneteller of the royal family discovered some omen, and came up with some astronomical omen that "the number table is dead, and the difference should be established".

  But they have calculated thousands of times, but they didn't calculate that the scene will be like this:

  A young, outrageous oriental started the conversation, and according to Goss, this person was not only the proposer of the cooperation, but also occupied the decision-making power of today's talks.

  How is this possible?

  If you were a white or mixed-race boy of about the same age, Babbage could still guess from the perspective of descendants of nobles, but an Oriental

  Seeing that Babbage was a little confused, Gauss thought for a while and added:

   "By the way, Charles, you should know the 'Conan Star' discovered by the Cambridge University organization three days ago, right?"

  Babbage nodded and replied:

   "Of course I know, even the workers in London are discussing it now."

  Gauss said that he patted Xu Yun on the shoulder and explained:

   "Luo Feng is the organizer of the stargazing event. Without his proposal, we would not have been able to find that planet."

   Babbage was stunned for a few seconds when he heard the words, and then he slapped his forehead suddenly, and said:

   "So he, Luo Feng, is a descendant of Mr. Fat Yu?"

   At this time, three days have passed since the night of Pluto observation, and the news about that night has also spread to all parties.

  Although the European Astronomical Society, out of prudence, declared that more detailed observations are needed to make a final determination, civil and individual astronomers have no such concerns.

  They conducted observations as early as the night when the news appeared in the newspaper, and the observation results proved one point without exception:

  'Conan' is indeed an undiscovered planet!

  During the past three days.

   As large as the Times, as small as the Wilshire newspaper.

  All European paper media are frantically reporting this incident, which can be called a massacre.

  Common words in the British media include Cambridge University, George Biddle Airy, Faraday, Earl Ellis and so on.

  The German media focused on the German reinforcements such as Gauss, Riemann, and Jacobi.

  George Biddle Airy's hat of shame has been completely removed, and the director of the Greenwich Observatory has once again become a hero.

  As for the Ellis and his sons, they were more unlucky-many public opinion believed that it was their obstruction that led to the lack of manpower in the Department of Mathematics recruited by Gewushe, which gave Gauss and other Germans the opportunity to intervene.

  The glory that should have belonged exclusively to the British Empire is now half divided by Germany.

   Although these remarks would not cause substantial harm to the Ellis family, they made them somewhat ashamed for a while.

   Compared with paper media, Babbage understands more.

  His good friend John Herschel approached him enthusiastically the next day and told him about it.

do not forget.

  John Herschel's father was William Herschel, the discoverer of Uranus.

  Babbage roughly learned the details of the incident from John Herschel, and also heard that there was such an oriental student with a "offspring of a fat fish", who played an important role in the whole process.

   It's just that Babbage's mind was focused on the details of today's meeting with the head of Barclays Bank, and his attitude was relatively perfunctory.

   Don't say it's supernatural, but it's true that I didn't pay too much attention to it.

  But now hearing what Gauss said, this part of the memory will be revived.

  Think here.

   Babbage looked at Xu Yun involuntarily with a more formal gaze:

  The offspring of that legendary man

   Perhaps he could really see the potential of the Analytical Engine?

   Then he forcibly suppressed his excitement, pretending to be calm and asked Xu Yun:

   "Luo Feng and Mr. Luo Feng, I don't know what type of analysis machine you want us to design?"

  Xu Yun glanced at Babbage's clenched knuckles, took out a few pieces of paper from his side, put them on the table and pushed them over with one finger:

   "Mr. Charles, the requirements are all here, you can take a look first."

  Babbage and Ada looked at each other, and took the paper with some trepidation and read it.

   "It can store 10,000 50-digit numbers, and can automatically solve 500 variables."

   "Each number requires 35 digits, and the operation speed is two to three times per second"

   "In addition, it is necessary to be able to verify at least two coordinate systems among ecliptic coordinates, galactic coordinates, and equatorial coordinates."

   After quietly reading the requirements listed by Xu Yun, Babbage's face was a little cloudy.

after awhile.

  His shoulders collapsed suddenly, and he exhaled weakly, but his expression appeared very sincere:

   "Sorry, Mr. Luo Feng."

   "Although I really want to get this investment, I don't want to cheat you—to tell you the truth, let alone 100% of the requirements on paper, we can't even do 20% now"

   Ada on the side opened his mouth when he saw this, wanting to say something.

   But in the end still did not speak.

  As Babbage said.

   With the data given by Xu Yun, there is no possibility of it being completed at all.

   According to Babbage's design.

  His 'Analytical Engine' has three modules:

  One is the gear-type "repository", Babbage called it "warehouse".

   is where the data is stored.

   The second part of the Analytical Engine is the so-called "computing room", which was named "workshop" by Babbage.

  Its basic principle is similar to Pascal's wheel, which uses the meshing, rotation, translation and other methods between gears to perform digital operations.

  The third part Babbage did not name it specifically, and its function is to control the sequence of calculation operations with the "0" and "1" in the Jaccard punched card, similar to the controller in a computer.

  The computing power comes from the steam engine, and Ada is in charge of the other passwords.

   Among the requirements given by Xu Yun.

  Data storage is the simplest and the only link that can be done.

  Babbage's data storage carrier is gears, each gear can store 10 numbers, and the array composed of gears can store a total of 1000 50-digit numbers.

  If you want to expand to the 10,000 requested by Xu Yun, you only need to add gears—this is not difficult when the funds are sufficient.

   But the rest of the data is pretty out of the box.

  Currently, Babbage can only achieve 24 digits of calculation accuracy, automatically solve 80 variables, and the rest of the other links have not even produced specific results.

   Really calculate the words.

  His equipment can only solve second-order difference calculations and produce seven-digit results, which is already the limit.

   Actually.

  Babbage was not the kind of person with such a noble character. For example, in order to obtain more profits, he even cut corners in the chess toys he sold.

   But as the saying goes.

  Scholar dies for his confidant.

  After encountering countless rejections and cold looks, Babbage suddenly learned that Cambridge University was willing to invest such a large sum of money in himself. While being moved in his heart, Babbage also rarely thought about it for the investor:

   Once so much money is wasted, Xu Yun, who is the main leader of the project, may have a difficult life.

   And across from him.

   Seeing Babbage's complex expression, Xu Yun shook his head with emotion.

   Three days ago.

  After setting a one-year contract with Gauss, he found that there was a very real problem before him:

  Now there are 34 top-level observatories in Europe. Under the mobilization of Gauss and Faraday, tens of thousands or even hundreds of thousands of photos may be taken a year.

  The calculation volume and error of this base number cannot be solved by finding a few more mathematicians.

at the same time.

  Xu Yun knows better than anyone else that the mysterious planet is extremely far away from the earth, not as simple as one or two astronomical units away from Pluto.

  Although the specific location of the planet has not been discovered in later generations, the general area can still be locked down through abnormal celestial bodies.

   Therefore, the analysis of data is difficult to solve by manpower alone.

  This is a very realistic problem, not something that you can yell a few slogans and get over it with a burst of enthusiasm.

   So it's natural.

  Xu Yun thought of the combination of Babbage and Ada.

to be frank.

   Throughout the 19th century, even Babbage and Ada themselves probably didn't know what kind of business they were engaged in.

   Their thinking is too advanced, a full hundred years ahead, and there is a fault with the entire era.

  In the words of a certain red hair, it is a product that should not exist in this piece of ancient history.

  They thought they were making mountaineering boots, and after turning over a hill, a cliff appeared in front of them, and they sighed and came to a dead end.

   But only Xu Yun knows.

  What they created is actually a pair of wings, and the vast sky is their real route.

  So he asked Gauss and Faraday to guarantee, and won an investment quota of 50,000 pounds from Trinity College.

  One is the first person in mathematics today, and the other is the first person in physics today. It is too easy to complete this task.

   This is equivalent to in later generations, one day Qiu Chengtong and Yang Lao jointly found a school, saying that you gave me 50 million funds and I tried to find the ninth planet. It may not be successful but it may not necessarily fail. What should I do?

joke.

  Don't talk about Qingbei Jiaotongfu or 985211, even Wanzhou Grilled Fish Academy can take out this money in minutes.

  The line of sight returns to reality.

  Looking at Babbage with a somewhat 'sad' expression.

  Xu Yun smiled slightly, pulled out another document from his body like Doraemon, and handed it to Babbage:

   "Mr. Babbage, please read this first."

  Babbage took the document with a puzzled expression, glanced at it subconsciously, and could not take his eyes off it:

   "This is"

   Ada on the side also rushed over when he saw this, and fell into the same state as Babbage within a few seconds.

  Earl Lovelace sat quietly at the side, smiling and watching his wife and Babbage blushing and studying.

  Xu Yun didn't bother them, and just waited in his seat.

   Xu Yun of the later generations is a pure computer novice, and he doesn't have much knowledge about computers.

   I barely know that the bigger the graphics card is, the better. The 3060 has a high probability of being a mining card.

   As for computer technology

   You will use F12 to change the inspection element, you will use Ctrl+C to copy the text, and the rest will be gone.

Oh, right.

   I also know that if the screen of the computer is black, it may be that the memory stick is loose, um, and then it is really gone.

   But when it comes to the analysis engine, he still knows a little bit.

  Because this thing is very famous in the DIY circle.

  In principle, it first considers the square of integers.

   For example, first list a row of numbers:

  1, 4, 9, 16, 25, 36, 49, 64 and so on.

  Elementary school students can see that their law is the square of one to eight.

   Then, by subtracting the immediately preceding number from the following number, a new difference series can be obtained, which is called the first difference series.

   It consists of numbers 3, 5, 7, 9, 11, 13, 15, etc.

   Do the above operation again to get the second difference series.

   They are both constants equal to 2.

   That is to say.

   If we want to transition from the number 5 to the following number 7, we must add the constant difference 2 in front.

  Similarly, if you go from the square number 9 to the square number 16, you must add the difference 7 to the former.

   That is, the previous difference of 5, plus the constant difference of 2.

   This rule is summarized on the equipment, which is the prototype of the analysis engine or difference engine.

  Assume that the machine has three turntables, named A, B, and C, and each turntable has a scale.

   For example, there are a thousand scales, and a pointer can pass between these scales.

  C and B should also have a set hammer with the same number of strokes as the scale indicated by the pointer.

  Every time the positioning hammer of turntable C is knocked, the pointer of turntable B will advance by one step;

   Same.

  The pointer of turntable A will advance by one step every time the positioning hammer of turntable B strikes.

  Assume that pointer C is placed on scale 2, pointer B is placed on scale 5, and pointer A is placed on scale 9.

   Then let the positioning hammer of turntable C strike.

  Twice it strikes, pointer B will cross 2 marks - the latter will now indicate the number 7.

   If the positioning hammer of turntable B is allowed to continue striking, it will strike seven times.

During this period.

   Pointer A will advance seven spaces.

  Since the pointer A is initially positioned at 9, the number 16 will be obtained, which is the square number after 9.

   And as long as these operations are repeated infinitely, a very simple method can be used to continuously reproduce the sequence of square numbers.

   That is, when something thin and pointed moves, the positioning hammer will make a crackling sound, and then output something.

  The solution given by Xu Yun includes many optimizations in this regard by later generations.

   For example, the formula T=x^2+x+41 is summarized.

   Another example is changing the turntable into a variable column to reduce the difficulty of the process.

  For example, the idea of ​​introducing machines is also added.

  Analytical machines have always been a popular DIY project in later generations, and the DIY circle sometimes thinks strangely.

  Like later generations, you can buy high-precision gears on a certain treasure, but DIY enthusiasts of analytical machines like to buy that kind of equipment with lower precision, and achieve the effect by modifying the channel-the euphemistic name is retro.

  The closer the level of craftsmanship is to the 19th century, the better you will be.

  At the same time, compared with foreign DIY circles, the domestic situation is even more difficult.

  Because domestic electricity control is very strict these days.

  For example, a certain leaf or mining machine consumes a lot of electricity, so once there is an abnormal electricity consumption in the community, basically someone will come to the community to send warmth soon.

   Therefore, domestic analysis machine enthusiasts should also pursue high efficiency and energy saving while pursuing retro

  As a veteran enthusiast in the DIY circle, Xu Yun can say that these optimized solutions can be said to be at his fingertips.

  He didn't even use the reward for returning to reality for a short time, so he wrote a bunch of optimized content by himself.

   And this part of the optimization plan, which can be called entry-level, is undoubtedly a treasure for Babbage and Ada.

   "Write the coefficients m, n, d, m', n', d' on 8 bars, so that n and n' are repeated twice"

   "m enters mn' and md', n' enters mn' and n', these coefficients will be assigned in V0 and V4 columns."

   More than ten minutes passed.

   Babbage suddenly raised his head, looking at Xu Yun with bloodshot eyes:

   "Mr. Luo Feng, where did your ideas come from? It's really too subtle!"

  Xu Yunjian said that he was sure, raised his eyelids to look at him, and explained:

   "It's just some ideas left by the ancestor of Fat Yu. He has a friend named Qiu Sheng who has been single, so the ancestor of Fat Yu wants to find him a second-dimensional wife and forget it. Let's not talk about it."

   "Mr. Charles, do these things help you?"

   Babbage nodded heavily, not seeing the slightest look of frustration before, and said quickly:

   "It's very helpful, Mr. Luo Feng. With these things, the previous standards may be possible!"

  Xu Yun smiled slightly, understanding what he meant:

   "So Mr. Babbage, you decide to take this investment?"

  Babbage turned his head and looked at Ada and the little transparent Earl Lovelace, took a deep breath, and said:

   "Student Luo Feng, I, Charles Babbage, swear in the name of the Babbage family that I will do my best to complete the research and development of the Analytical Engine!"

   Half an hour later.

   Seeing Babbage's name on the investment contract, Xu Yun felt relieved.

   Both parties agree in the contract.

   Babbage and Ada will move to the small town of Cambridge within a week. At that time, Cambridge University will pay the initial construction fee of 10,000 pounds, and at the same time, medical personnel will be arranged to conduct a physical examination on them.

   After all, follow the historical track.

   In two years, Ada will die due to physical deterioration, at the age of 36.

  Although Ada does not know whether she has cervical cancer, it is always right to have an examination and recuperation.

  Ada's fatal cause of death was excessive blood loss during the treatment of the disease. In theory, there is still hope for rescue.

  In addition, the delivery date signed by Babbage and Xu Yun is November next year, that is, 11 months later, one month earlier than the time agreed with Gauss.

all in all.

   Right now, all preparations have been completed, and the rest is to see the results.

  After leaving the office.

  Xu Yun glanced at the sky and said with emotion:

   "Do your best, know the destiny."

Note:

   Looking for a monthly pass, I will try to update my 4D every day on the 27th!
